TObjectFloatMapDecorator (Trove 3.0.3)

java.lang.Object
- java.util.AbstractMap<K,java.lang.Float>
- - gnu.trove.decorator.TObjectFloatMapDecorator<K>

All Implemented Interfaces:

java.io.Externalizable, java.io.Serializable, java.lang.Cloneable, java.util.Map<K,java.lang.Float>
```
public class TObjectFloatMapDecorator<K>
extends java.util.AbstractMap<K,java.lang.Float>
implements java.util.Map<K,java.lang.Float>, java.io.Externalizable, java.lang.Cloneable
```
Wrapper class to make a TObjectFloatMap conform to the java.util.Map API. This class simply decorates an underlying TObjectFloatMap and translates the Object-based APIs into their Trove primitive analogs.
Note that wrapping and unwrapping primitive values is extremely inefficient. If possible, users of this class should override the appropriate methods in this class and use a table of canonical values.
